Another object of this invention is to provide a clip or other metalspring anchoring member having an opening therein and also a projectionor prong for the purpose mentioned, both of which can be formed in asingle manufacturing operation at substantially the same cost as that ofpunching the nail holes in previous devices.

I have found that a practical and economical method of forming both anopening and a perpendicular prong in a flat metal spring anchoring clipor strip is to stamp or punch such prong from the fiat base of the clipor similar anchoring member, thereby providing not only an integralelement in the clip or other member which can 2' be -nnbeddedsm-a--wooden:1irame; asnthehinitialr nieansof attaching thememberto'theHr-amepbuti also prov-iding a suitable opening in the baseof the Jelip-or other member;- form-ed -biy :the stamp ing: orpunch-ingoperations through which a nail on the like maybe insertedinto 1 theframe as: a permanent: fastening: means;- sThe? cost "of tha singleoperation in providing bothz the opening and the prong does not exceedthatlof 'the preview ous operation of punching the nail hole? only;

other objects and? advantagesmf my-invention will be apparent-from thefollowing specification and "reference-to the accompanying drawings in"which I V 1' is---an-=-enlarged p'erspective et -one form of springanchoring clip with my invention applied thereto;

Fig. 2 is a sectional view of the clip shown in Fig. 1 as attached to awooden frame with a spring anchored therein;

Fig. 3 is a perspective view of another form of spring anchoring clipwith my invention applied thereto;

Fig. 4 is a sectional View of the clip shown in Fig. 3 as attached to afurniture frame with a spring anchored therein; and

Fig. 5 is a perspective view of another form of spring supporting memberwith my invention applied thereto.

In the drawings the clips, or spring supporting members illustrated aretypical of those previously provided with only a nail hole for theinsertion of a nail into a frame as the initial 3 and only means ofattachment to a frame. It should be understood that those illustratedare only a few of the various clips and devices carrying means forengaging and holding the end of a spring and having a flat base portionto which my invention can be applied.

The clip l illustrated in Figs. 1 and 2 has a fiat base I2 which extendsoutwardly from a U- shaped bend l4 through the opposed walls of whichare registering openings I6. Adjacent the outer end of the base portionI2 is a depending prong l8 which is arranged to be driven into a frameby a hammer, or the like. The clip l0 may be made out of sheet steel orother suitable metal and the prong l8 stamped or punched from the baseof the clip, thereby forming an opening 22 adjacent the prong orprojection. This opening permits the insertion therethrough of suitableretaining means, such as a nail, screw or the like 24 into the frame 20,when it is desired to effect permanent fastening of the clip to theframe 20. With this form of clip an elongated spring 26, having atransversely extending end portion 28, is inserted in the open end ofthe U-shaped bend or hook [4, after which a nail, or the like 30 isdriven through the openings l6 into the frame 20, thereby slightlyfiattening the overlapping portion of the clip, as shown in Fig. 2. I

The clip 32, illustrated in Figs. 3 and 4 also has a flat baseportion-34 extending outwardly and downwardly from a U-shaped bend 36for engagement with one end of an elongated wire spring 38, having atransversely extending portion 39, as shown more clearly in dotted linesin Fig. 3. A pair of integral, perpendicular prongs 40 may be struckinwardly from the base 34, these prongs being arranged to be driven by ahammer, or the like, into a wooden frame 42. The stamping operationleaves an opening 44 adjacent each prong 40 through which nails, or thelike (shown dotted may be driven into the frame 42.

The spring supporting member 41 illustrated in Fig. consists of a flatmetal strip having fingers 48 bent over the lower coils of a number ofhelical springs 50. Adjacent each end of the strip 41 is a pair ofperpendicularly arranged prongs 52 struck from the fiat metal andleaving openings 54 through which nails, screws or other suitablefastening elements 56 (shown dotted) may be inserted into a frame 58.

In the use of my improved spring anchoring members a workman will carryonly a supply of clips, such as those illustrated in Figs. 1 to 4, or asupply of strips, such as the one illustrated in Fig. 5, and a hammer orother tool for forcing the prongs of the anchoring members into a 4frame made of wooden or other penetrable material, when initiallyattaching the members to the furniture frames. His entire working timemay be confined to such initial installations. Since he has only toplace a clip, or similar device provided with the prongs and openings,in position and drive the prong into a frame, the number of anchoringdevices that he can install in a given time is greatly increased, ascompared with the use of previous anchoring devices, because of theelimination of the need for carrying and using a supply of nails.Another workman may subsequently insert nails or the like through theopenings in the devices to complete the permanent installation.

As previously mentioned, my invention is applicable to a number offormsofclips and other spring anchoring devices inaddition to the formsillustrated in thedrawings. Therefore, it should be understood that myinvention is not limited to the specific embodiments shown and.described.

I claim: a V

A metal U-shaped clip of uniform width-for attachment to a non-metallicframe, said clip including a base having at one end an upwardly bentportion overlapping said base and providing,

a space arranged to receive an end portion of an elongated spring, saidbase having a portion extending outwardly from said overlapped portionand provided with a struck out depending prong and forming an openingfor receiving a retaining member, said prong being adapted to beinitially embedded into said frame and said opening adapted to receive aretaining member for permanently securing the clip to said frame, saidvoverlapped portion and said base havingvertically aligned openings inthe same vertical plane with said prong for receiving an auxiliaryretaining member arranged to be embedded in the frame and which coactswith said prong and said first mentioned retaining member for firmlyconnecting the clip to said frame.
